In order to realize the real.time tracking and fore.casting of net load with distributed power bus, in the light of the busload with distributed photovoltaic power grid, according to the linearand nonlinear properties of net load inherent, the autoregressivemoving average with the phase space reconstruction and support vec.tor machine bus.bar net load forecasting method is proposed.Firstly,based on the historical net load data, the ARIMA model is estab.lished to forecast the linear components of the net load.Then, thephase space of the nonlinear components is reconstructed by CCmethod.Finally, the nonlinear part is forecasted by the SVR model.The results of data modeling show that the proposed ARIMA .CC_SVR forecasting model is suitable for the net load of the bus.barwith distributed PV components.
